Like ietters designate corresponding ports in ell ot' the figures. A i i s The leading features of my4 invention-consist in o niortewhox moved upward or-oiong in close proximity to, und peraliei with, the well or surface to he piostered between or by the guide-ways of u frame or stond; a

follower, inside of the mortar-box, which is forced forward by tiie'uipncrd movement of the `mortar-,box at such. l o rn'te os to supply mortar just sucient to spread the surface to the proper and uniform thickness; and o.' trowel for forming and smoothing the surface of the plaster, el! suhstentiuiiy cshereinofter specified` Aihe method of constructing and arranging these main ports of my invention muy he vuriedin many oorticulurs; but I will proceed to describe the construction, orron gement, and operation of the invention usl I have embodied it in practice, and represented in the accompanying drawings.

First, the frame or stond has chose, A, neer the iloor, to be provided with casters or friction-wheels, ma,

so that the stond muy be readily shifted from one position to another, and also providcd'withpoints or dogs in b, to be screwed or forced down to thel door, end thusto hold the stond. securely iu u. xedposition when it is located in any place for operation. When the rali in front ofthe machine has been plastered thc dogs b are screwed or'rnised up owny from the looreo as to allow the stand to be moved to another position. The 'guide- 'ways ore required to extend from the ceso A nearly or quite up to the ceiling', .and to be secured et the lupper.

cud coeurotol in osition' ond since the hei hte of rooms diiicr reotl itl `is necessiti' to have these nido-- p 1 g y y g ways adjustable in length.' For this purpose each nayis composed of two purts, oixed standard, und an extension standard, B, one euch of which iu represented on oooh side of the machine. `The fixed standard C muy be tubular, ondthc extension standard slide up und dormA therein; hut I here .represented the tn'o stuud? srds us situutcd side by side, ond coupled together hy a. metallic hunch, M, one edge` of which is perniunently secured in the cittcnsio'n standard B, und theotheredge tits into o groove iu the edge or side of the xcd i stundurd, there being ny feather or projection, w, on one side of the ianeh to tit into o corresponding `depression ot one side of the stzindor'd groove, as shown in figs. if und 5, to keep the tlanoh in piece in the' standard. The coupling flonh, with the extension standard Bfslidcs freelg,T in the grooved standard C, und in order to .extend or retract the standard B :i set of rack-teeth, m, iig. 7, is formed on or inl'the iunch M, and into this rock o driyingpinion, mounted in the fixed stondord C, and turned by o crank, v, is geared, as specially indicated by red lines in the seme .figuren The standards B B are represented in red lines in iig. 2v as extended; and tlioreere points upon the upper ends thereof to'strihe und pierce the ceiling euiiiciently'to hold` the ways firmly inposition at the upper end. The extension standard muy bc holdup by looking the reising ninions a?, n

The mortaio-imi: may be modo of cost iron, sheet steel, cir-other snitoolcqncieriaii Third, the followerv K, for forcing the morini" formi-ddii tho nxf-rtv.i-box, is oi'ronged vertically cdgcwise, and its 'edges accurately ht the top, bottom, ond ands oi" the :norton-b hul. not so closely but that il.' will move fox-Word and backward freely therein.

I raccomplish this :mtomotiooily byl tho moi-ornent ol' tho morini-hon itoll, oo i: is drown upward, substantially as follows: There are projecting racks 1- 1 on the bock of tho follower extending boch o oufcieni. distacco to the rem" of the mortar-box, ond gcoing into pinicns c s on c shaft, S, hot also has o. cogyheel o1. pinion, u, into which o driving-pinion, o, on n. parallel :ihn-ft, gears. 0c lic lutter shrill. .is ccnrcd coothoc pinion, P, which gears into two moins, d c, attached respectively to racl:-stonflnls ci the bacia of tho from@ or aloud.

'i und 3, or an quivalent device. Whoo the ciando-'fd l) io ontondod, tho pinion l? travelo at the bottom only on the rock e of the stando-MD; in tho middle, on both melts; ond n?. the iop, only on :Elio x'ocl: i of'tho standard D. The `travelling of' the pinion on bho rocks ci' e, ch il is rovolvod, consequently causes the shaft t to rcvolve, and the pinions s thcicon drive the rocks 2". foward. Thus tho follower il iomoiodforwnrd equally l ot'both ends, and just in proportion to -hc upward Imovoinmi. ci" tho molino-box. The a'clotivc mio ot which the follower is caused to trovcl'dpcnds on tho rcloiiyc. .o of zho pinions ll,v,-u, ond o of so phot, 'by changing the pinions s s for others larger oi: omoiler, 'che folic-wor will. room fouler or siowor in relation' to the movement oi' thomortnr-lzox up'n'zircl, and thus will lay cho planter tmlor or thinner, required. When the mortar-tbox is drown down, the follower l is drown bac: therein hg; como moons-which drivcc it forward, lem/ing tho moritavbbonfogoin ready to rcooivo another chorgc ci mon the mortar-honi is divided into camcom ments, there should 'be c'follower foreach compartment, und each follower has stack orraclis gearing into corresponding pinions en the shaft t, es indicated by red lines in iig. 4.

Fourth, the trowel I is situated just in front, and below the mortar-box- H. Its upper edge is bevelled," curved, orshurpened, so that it will cleave ond separnte the mortar, und its front surface is set c. little obliquely,

so that its lower edge projects forward soinewhnt more than the upper edge, in order that itmay, in ascending,

compress the vsurface of the plaster, :ind thereby finish it more smoothly. `Its length is equal Aor nearly eqnrnl to, yor sometimes greater thun, the entire width oi` the-frame or stand, so that it muy finish close up to e cerner of the room, or other projecting surl'nce; ond in order thot it muy sometimes iinish even somewhat fuiither thun the irame or stand con extend, in one direction, I have provided means by which, it may be adjusted endwise, or transversely to the stand. As shown in tig. 5, this is accomplished'uby having the tron-'els inountedon stationary guides 3 3, which project downward from the mortel-box and t in slots 4 dof the trowel, the 'slots being longer then the width of'the guides, se esl to'allow side movement o? the trowel in' either direction.. Thorn-by connecting the trowel, through springs 'l T, with u trnvellingnut, U, on a stationery screw, Q, l:md turningV the said screw'Uay e vcrenkdmnrlle, y, er equivalent means) in one or the 'other direction, the ,trourel'l is moved or adjusted ideither direction required. The, guides 3 3 muy be elastic, so as to give elssticity-tol the trowcl nnd allow it to yield, if it strikes o. stone in the mortar. The projection of .the trowel. lbelow the` mortarfh'ox enables me to begin the plostering es neer to the door es` necessary, 'although thomortenbox meyjr" not be`- brought down to the floor by-efew inches. The mortar-box, with the strong pressure of'its Yfollower', lnys the plaster upon the well thoroughly, and the oiiice of the trowcl is to seperate thermortor, ondforxn und s'mooth the plastered sui-fece; but although the mortar-box con Ihe raised close up tothe ceiling, the trowel, if kept stationery below the mortar-box, cnnnot finish that portion of the sui-fece of the plaster which lies in front of vthe mortar-box when at its extreme height. This portion might he smoothed or finished by hund; hut'I have Yprovided means by which, when the mortar-box reaches the ceiling, the tronei is moved upward in front thereo?,

so es to finish the surface close up to the ceiling. The drawings represent on outomu'tic device for accomplishing i l this purpose.

Thus, in gs. 5 ond 6, springs TVT are hinged tothe lower edge ci' the -troweh at z c, neer its ends. These: i

springs are secured under the mortonbox, und oresoset thnt they will spring thetrorrel, when free, up in front l of the mortar-box. When the trowel is brought down to its ordinary position beiowthe mortar-box, itis held in position by o sprlng-cntch, (or cntches,) o, attached to the mortar-box and holding against n notch or ;n'ojecv tion, 2, at the lower edge of the tro'wel. By tripping this catch o, the trowel will be forced Aupwsrd immedintely by the force oi. the springsT T. Totrip the catch automatically, o lever, S, is pivoted thereto, at 1, land `to c. projection of Vthe metter-box et 20; end'it is so shped that, on depressing its roar ond, its front end willbe moved 4lm'clsword, so este vdren' the spring-catch o from the notch or projection '2 of the trowel, ond set the letter free. A vertical rod, R, ia pivoted nt 19 to the lever S, ondv extends upwards little above the top of the mortar-box, ns shown in iig. 5, where it is 'held and guided in n loop or hole, so that it will slide freely up and down. Thus, just before the mertanbox reaches' the ceiling, the rod R strikes it, and, being depressed tliore`by,f. v

it moves thelevor S und trips the tronebcutch. As the trcnel ascendsvin front of the mortar-box it in guided in position'by the front edges 21 (iig. 6) thereof, which project forward most stille upper edge, csshown, and Y thereby conse the trowel, when in that position, to project forvrord most at the 'upper edge. Then, on letting down thehiortar-box, the'trowel glides smoothly over the surfsee 'of the plaster justforined Without injury thereto, but rntlier improving the finish thereof. v Or, if preferred, the stand maybe set free and moved from pince before lowering the mortar-box, bypushing sidewise along nearly parallel with thel well, being careful notl to allow the trowel to injure the plastered surface. l'. employ the same machine for plustering ceilings. For this purpose, ityhns to be mounted on n supporting apparatus, a. formell whichl have represented in figs. 8, 9,

end`10. j This apparatus consists of a. standard frame, V, suitsblyrbreeed bothv'fwsys by 'braces 11 nud 12, Vand sliding or extension standards, W W, on which the plestering machine is mountedysnd which are raised and' adjusted by reeks on the couplingdlanches 16 16, ond bypinions 15 15, similar in. construction and action vto those described for raising the extension standards B B D in the Plastering inrlfehine.` lAs there srcl two of these extension standards ot each end of the supporting frame, end since all should be elevated equally utili uliolhly together, the two .elevating rocks 15 15, et each end, sro secured on one shaft, X, end the two shafts X X et wheels 14' 1d 'on Vthe shaft, into which pawls 10 10 ctch, to hold the stnndords at the exact height required.

0n the upper ends of the extension stendardo W W are pins or equivalent projections, 24 24, which lit into holes or depressions in the bool: side of the frame .or stond of the Plastering machine.. By this or nnequivalent moons the plnstering machine is secured on the extensionv ntnnderds, so that, when ullounted horizontally, with 'its front side' upward, es shown `in g. 8, 'it will be rruly held on scid standards. When time mounted, the mortar-box is dreun to the lower end (es when in s. verticcl position) of the Plastering-frame, und is filled with mortar. The shafts X X are then turned so es to raise ell the standards W W equclly, thereby lifting the plaster-ing machine till it is brought close up to the ceiling, es determined by thefgsugesL L. The mortar-box'4 is then moved nlong by turning the crank G, as in Plastering rerticsl wells, the machine aoting'in precisely the somo incliner as'in said vertical position. l3nt indi-owing boch the empty mortu'rbox, since' its owns-eight l cannot here cleet. that movement, o. cord, cs shown in :ed lines, 5g. 8, passing over s pulley et the bottom 'of the frame of the mnchine,'may' be employed for that purpose. The supporting standards ore then loweredfer enough to enable the mortar-box to be lied conveniently, und the supporting-frame V is then moved on'costers 13 to o. new' position.` It may then be secured in position by points or dogs '17, (Eg. 9.) The operntion is then repeated by raising the machine up tothe ceiling und plcsteriug. another breadth Ves before. The 'zucchine is hel ppt@ the ceiling by the pmvls 10 10 and ratchetwheel'flfi '14, b'f'ore describempx;man equiyalonts; ami, .fvgicccefgmy 01j geaievible, there may be points or dogs 'for eecuringtbo machine firmly in positiowgnder ythe "criiing, ont?. prewfn my sido movement' or swuyig, similar to 'those described for'boldng the extension stondt'lrs B-Bto the `Ziling inlplasterig vertical-walls.
